CARBOLAB
In the prospect of climate change mitigation, greenhouse gas emissions could be reduced by the geological storage of CO2.One of the promising variants of this technique is the injection of CO2 in deep unmineable coal seams.There, anthropogenic CO2 can be stored mostly by adsorption, this releasing CH4 that can be used for energy production.This method is been tested worldwide, but European coal deposits have received few interest (excepted the RECOPOL project).The processes generated during and after CO2 injection are still not well understood, nor are the opportunities in Europe.
The Carbolab project is supported by the European Fund for Coal and Steel, and involves 6 partners from three European countries, research centers as well as private companies.Its aim is to inject a significant (though not pilot-related) quantity of CO2 into a coal seam that will be pre-equipped for continuous monitoring.Putting devices in the near vicinity of the CO2 plume, only a few metres away, will allow data of much higher quality and density to be collected than in the case of injection from the surface, and to adapt the injected flow and the monitoring protocol to the evolution of the CO2 plume.
Analysis of the long-term safety of the CO2 storage in coal seams:•Simulation of behaviour, sizing of parameters for monitoring norms, risk assessment•Criteria and standards for ECBM site certification; recommendations for monitoring.
Characterization of the initial state of the site:•Synthesis of existing geological, sorption-desorption processes, and geomechanical data•Acquisition of complementary data from geology, geophysics, geochemistry, coal and gas characterization, hydrodynamics
The project started 1st July 2009 for 4 years
